The “Prehensile Foot” is an interesting term that was completely new to me after 13 years of college and two decades in the fitness and health business until a couple years ago.  Defined, “prehensile” means “to grasp.”  Toes are basically designed to grasp the ground and assist in balance and throughout the gait process.  Talk to any good martial artist about “root” or base, and they will tell you about the importance of the feet to screw into the ground—or root—rip and grip, or something to this effect.  Don’t underestimate toe power!  One of the best things you can for both health and safety is to let your toes do their job—grasp!  Most shoes basically ruin our ability to grasp with toes because they are too narrow and/or too short.  Over time this alters the shape of the foot and removes the “prehensile” qualities. *See my “Products Section” for more information.
